On Earth, the gravitational field intensity is 9.8 N/kg. Mercury has a mass of 3.28 x 1023 kg and a radius of 2.57 x 106 m. Calculate the gravitational field intensity on Mercury in N/kg.(adsbygoogle = window.adsbygoogle || []).push({});

Given:

g = 9.8 N/kg (on earth)

m = 3.28 x 10^23 Kg

d = 2.57 x 10^6m

Required:

g = ?

Solution:

?

I was just wondering what given would be used and what equation would you use to solve this question; F = Gm1m2 / d^2 or F = mg.
